Abstract
A color correction system includes an identical first color chart (FCC) and a second color chart (SCC), and a color correction unit (CCU). The FCC and the subject are positioned in view of a source image capture device (SICD) at a source location. The SCC and a display unit are positioned in view of a destination image capture device (DICD) at the destination location. The SICD captures and transmits source image content (SIC) of the subject and the FCC to the CCU at the destination location via a network. The DICD captures destination image content (DIC) of the SCC and the SIC displayed on the display unit. The CCU generates calibration parameters by comparing the FCC extracted from the SIC and/or the DIC, with the SCC extracted from the DIC, and corrects the SIC of the subject and gamma parameters on the display unit using the generated calibration parameters.
